      Description

      The first release of Mumak (MAPREDUCE-728) introduces some coupling between the core mapred code with Mumak code. Specifically, New constructors are added to JobTracker and JobInProgress to allow simulator to subclass and alter JT/JIP behavior. This could be a code maintenance overhead when new changes have to be ported to either the added constructors or the simulation subclasses.

      It would be nice to refactor the constructors of JobTracker and JobInProgress to avoid as much code duplication as possible.
